ZingProfessional Boat Hull Cleaner - Quart Bottle - Super Strength Cleaner Removes Marine Stains & Buildups on Boats, Effective on Zebra Mussels & Barnacles - Fresh & Salt Water Boats - (N074-Q12)

Cleans jet ski like a charm! Takes off all water scum.

I’m not a review writer. But this stuff is like magic. When we bought our boat about a year ago it already had some grime that needed to come off. Then we had it on the lake every weekend we could and never really took time time to try scrubbing grime. So we purchased this Zing and used it full strength with an applicator brush. I can NOT say enough good things. No scrubbing. Easy to use. Just apply to the brush, rub it in, let it sit for a few minutes and then rinse. The grime literally melted off.

Absolutely amazing! Easy to use but use gloves and glasses and good ventilation.

Used in a freshwater application for fall cleanup. This stuff worked awesome, easily took off everything, and mixed way weaker than reccomended. Best stuff I've ever used.

Works great. Keeps the hull very clean

Zing worked perfectly to remove a rust stain from well water on the front of our home. It removed the stain without taking off the paint which was excellent.

Cleaning the bottom of a boat works great .Make sure you cover your eyes and hands

Best ever product for cleaning boat hull
